Shadow of the Vampire (2000)

Synopsis: F. W. Murnau (John Malkovich) is struggling to create his silent classic "Nosferatu" on location in Eastern Europe. The director is obsessed with making this the most authentic vampire movie ever. To that end, Murnau has employed a real vampire, Max Schreck (Willem Dafoe), explaining to the crew that he is the ultimate of that new breed, the "method actor" -- trained by Stanislavsky himself. Schreck will appear only in character and only at night.
